Three Versions of Dual Independent Drivers:
- Dual Inverting + Enable (FAN3223)
The FAN3223-25 family of dual 4 A gate drivers is
designed to drive N-channel enhancement-mode
MOSFETs in low-side switching applications by
providing high peak current pulses during the short
switching intervals. The driver is available with either
TTL or CMOS input thresholds. Internal circuitry
provides an under-voltage lockout function by holding
the output LOW until the supply voltage is within the
operating range. In addition, the drivers feature matched
internal propagation delays between A and B channels

timing, such as synchronous rectifiers. This also
enables connecting two drivers in parallel to effectively
double the current capability driving a single MOSFET.
The FAN322X drivers incorporate MillerDrive?
architecture for the final output stage. This bipolar-
MOSFET combination provides high current during the
Miller plateau stage of the MOSFET turn-on / turn-off
process to minimize switching loss, while providing rail-
to-rail voltage swing and reverse current capability.
The FAN3223 offers two inverting drivers and the
FAN3224 offers two non-inverting drivers. Each device
has dual independent enable pins that default to ON if
not connected. In the FAN3225, each channel has dual

left unconnected, internal resistors bias the inputs such
